Cashing packages for npm registry with NGINX - node.js

Question

My project is javascript app.
I have lots of dependencies.
I/O for npm registry takes major portion of CI execution.
So my idea is to setup NGINX in front of npm registry and cache tgz files downloads.
Im running Ubuntu 14.04.
NGINX version is 1.4.6
This is my nginx configuration script
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# Logging Settings
##
# access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
include /etc/nginx/conf.d/*.conf;
# include /etc/nginx/sites-enabled/*;
# HTTP 1.1 support
proxy_http_version 1.1;
proxy_buffering off;
proxy_set_header Host $http_host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $proxy_connection;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $proxy_x_forwarded_proto;
proxy_set_header X-Forwarded-Ssl $proxy_x_forwarded_ssl;
proxy_set_header X-Forwarded-Port $proxy_x_forwarded_port;
# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
default $http_x_forwarded_proto;
'' $scheme;
}
# If we receive X-Forwarded-Port, pass it through; otherwise, pass along the
# server port the client connected to
map $http_x_forwarded_port $proxy_x_forwarded_port {
default $http_x_forwarded_port;
'' $server_port;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
default upgrade;
'' close;
}
# Set appropriate X-Forwarded-Ssl header
map $scheme $proxy_x_forwarded_ssl {
default off;
https on;
}
server {
listen 80 default_server;
location / {
access_log /var/log/nginx/root.log;
root /var/tmp/nginx/npm;
try_files $request_uri #fetch;
}
location #fetch {
internal;
proxy_pass http://nmregistry:4873$request_uri;
proxy_store /var/tmp/nginx/npm$request_uri;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_store_access user:rw group:rw all:r;
}
}
}
It works, i can install packages but they are not cached on NGINX machine.
Cant see any tgz files in /var/tmp/nginx/npm
What am i doing wrong here?

This is final version of configuration file.
The main problem was proxy_buffering on;
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
